A. swwa STOVE, HOT WATER AND STE/W1 HEATER, AND FURNACE,

APPLICATION FILED $55.1, i915 1 1 x vg g ggg Fatentea 2 SHEETSSHEET 2 plates. of metal, and preferably there are longitudinal bars or rods 10, 11 which form the upper longitudinal edges of the frame to which the cross wires of the sieve are con- .nected, the longitudinal wires of the sieve being connected with the heads 8, 9. Preferably also there are one or more longitudinal strengthening rods or strips 12 intermediate the longitudinal rods 10 and 11 and the cross wires of the sieve will preferably pass through holes in the intermediate strengthening rod 12. The heads 8, 9 of the sifter' are provided with the cylindrical journals 13, 1'4 by which the sifter is jour-' naled in hearings in the front and rear walls of the sifter chamber.

"Thesifter chamber 6 is formed with outmade. onthe arc of a circle of a somewhat larger radius than the radius of the sieve to allow for the rotary movement of the sieve within the chamber. The wall 15 on that side of the sifter' chamber which is toward the inner portion of the sieve, that is, on the oven side, as shown in the type of stove illustrated in the drawings, is made close enough to the side of the Sifter to merely allow a sufiicient clearance to permit the passage of small pieces of coal which may get through the sides of the si-fter, say a clearance of perhaps a half or three quarters of an inch. The other side wall 16, is made with an extension bulge so as toprovide a space 17 of some width between the circumference of the sifter and the said wall 16 to afford a passageway for the lumps of coal when dumped from the sifter after the ashes have been sifted, as will be hereinafter explained. The sifter will be of segment shape, as already mentioned, and will be preferably of somewhat more than a half cylmder, the journals 13, '14 of the sifter being in the line of the axis of the cylinder of which the sifter is a'segment. The chord 18 which ismeasured by the cross section V of the top or opemng of the sifter should 'be about'the same length as the width of the bottom of the fire chamberor the cross section of the grate. In order to guide the ashes from the grate'into the sifter and to prevent the ashes from falling down around the outside of'the sifter there are provided longitudinally of the sifter the inwardly sloping guides 19, 20 just below the grate and vjust above the entrance tothe sifter.

The front wall in which the sitter is journaled consists of a removable plate 21 which 7 covers the end of the. fire pot and of the sifter chamber, being of a somewhat banjo shape as shown in Fig. 2 of the drawings.

It is secured by screws 22 which pass a flaring upper edges of the side walls 29 of through holes in the said plate and screw into holes in one of the walls of the stove and by a button 49. The said front plate 21 is-made removable for the purpose of conwardly bulging side walls, each preferablyvenience in assembling the parts. The rear 1 wall 46 of the stove in which the rear end of the sifter is journaled is not necessarily removable. The front journal 13' passes through a hole inthe saidlbearing plate 21 and is provided with a sqhared'portion 23.

on its outer end to re'ceive, the key by which the sifter is rotated. 'It should preferably be made of the same size as the "squared end 5 of the grate journal'so that the same key may be used in turning the grate and the sifter.

Below the sifter chamber 6 is another chamber 24 opening directly out of the Sifter chamber which corresponds in locat on somewhat to that of the ordinary ash pit but which on account of the use to which it is put will be herein referred to as the,

drawer chamber or pan chamber. drawer or pan chamber contalns at least This one pan and preferably two pans 25, 26 one above'the other, the upper pan 25 being for.

the purpose of receiving the sifted ashes and the lower pan 26 being for the purpose of receiving the coal dumped from the sieve after the sifted ashes have been removed by taking out the pan 25. It is possible to get along with the use of one pan. only which shall be used both as an ash pan and a coal pan if. after the ashes have been siftedf the said pan is taken out and emptied of,

the ashes before the sifter is turned to dump the coal and then the pan is put back in place and the sifter is turned and the coal dumped into the same pan, but this is not so convenient as to provide two pans. The upper pan 25 slides on cleats or ledges 27 and is supported at the front on a cross ioo cleat or ledge 28. The bottom pan 26 may slide on the bottom of the chamber or on any'suitable ways 51. These pans should preferably be made of sheet metal compara; tively thin so as to make them as light as possible consistent with strength, and in order to avoid the'collection of ashes on the top of the side walls of the pan'the side walls 29 should preferably be made to bow inward, as shown in the drawings, the upper edge of the said walls being thin and the walls being curved inward, thereby pr'acti cally preventing any lodging of the ashes upon the top of the side walls of'the pan.

The top and bottom edges of the said curved side walls will fit as close to the sidewalls 47 of the drawer chamber as' is consistent with allowing the pans to slide in and out. The front 48 of the pan, however, will be finished square so as to make a closed front.

The interior of the drawer chamber is ofsomewhat greater width than the diameter of the sifter chamber so that the outwardly the pan will form an entrance wider than the sifter chamber and thereby insure the ashes going into the pan. There are also its 4 can be pulled outlike a drawer from a and should also be provided with a bail 39 which serves as a handle with which to carry the pan when it has been removed.

bail, however, should be adrop bail so that s when the pan is in its position in the pan chamber it will not project above the top edge of the pan. To this end the sides of the pan are formed with notches 40, 40 in with a handle or draw pull 38 so that they til suchtime as the new fire is started.

esk after the new fire is started the contents of.

the fire pet will serve as a stop for the rising of the dust so that the ashes can be sifted What I claim is: 1, a stove or other heating apparatus,

a ate, ef'rernovable ash panilocated at" so e distance below the grate, a sieve lo- -cated between the ,said grate and the said I 13mm receive thecoal and ashes the upper edges into which the bail willfthrough the grate, meanswhereby said sieve drop when turned down, the bail being piv-' oted, at its connection with the pan so th t it may be dropped down as described. n

order that the coal pan may, be usedto conveniently-pour the contents, thereof di- 'rectly into the stove without first dumping it into a coal hod the rear end of the pan is preferably formed with a rearwardly inclined wall 41 as shown in the drawings.

A hinged door 42 is provided which covers the entire front of the plate 21 which covers the end of the fire chamber and the ,sifter chamber, being hinged at 43, 4:3 to the ,2} frame of the stove and is swelled outwardly,

as'is clearly shown in Fig. 4 sothat it shall cover the ends of the grate journal and sifter journal and the stop device. The front of the drawer chamber is also closed by a so hinged door 44 which is swelled outwardly in similar manner to the door 42 so as to cover the front ends and draw pulls of the pans 25, 26.

While I have shown and described the sifter as being of a semi-cylindrical form not intend to and vibrated b a rocking movement, I do limited to, the particular form of sifter or to the particular mode of vibration.

So far as I am aware I am the first to provide within the heater a sifter intermediate between the fire chamber and the ash pan so that the ashes have to pass through the sifter after leaving thefire chamber and before reaching the ash pan and I intend to have the claims broadl cover such a combination.

By reason of t e sifter, the stove is some- I what hi her than would otherwise be necessary. 's afiords space for'a warm closet 53 below the oven 54 and above the bottom closets 55.

In the use of the ap aratus the grate may be shaken in an we known way and if this is done wh' e the fire is still alive the burning coal which is already left in the fire pot after the grate has been shaken will serve as a stop to prevent the dust rising through the grate during the sifting of the ashes and therefore the ashes maybe sifted immediately after shaking the grate without any trouble arising therefrom. If, however, the fire has gone out before the grate is shaken then t e grate should first be shaken and the dead coa dumped and the contents, 1 should be allowed to remain in the sifter unniay be agitated to sift'the ashes into-the an beneath, a second pan normally located irectly below said ash pan,- and means whereby .said sieve may be inverted so that when the ash pan is removed the remaining contents of the sieve may be dumped into the said second pan while said second pan is in its normal position.
